Windows Server Update Services (WSUS) is a Microsoft solution for applying updates to Windows hosts on a network. While excellent planning an implementation may lead to a successful deployment there may be times when troubleshooting failed updates may be necessary. Below is a list of three basic troubleshooting steps.
- Review the WindowsUpdate.log file (C:\Windows\WindowsUpdate.log).
- Confirm that your Software Update Point (SUP) is correctly registered in the registry (HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate).
- Verify that the client can connect to the WSUS website (http://server.fqdn:port/SimpleAuthWebService/SimpleAuth.asmx).
